I hate the emperor with a passion, you really left your daughter a dress knowing that it’s not according to the theme of the party and you basically humiliate her and say you love her mother but left them for years! You treat your youngest with love in from of everyone but ignore your oldest just because she doesn’t have gold eyes and powers? Smh I don’t think I’ll be able to like him no matter what he’s not gonna be like daddy Claude!

To be fair, he didn't know she was going to wear that dress to the party. It was just a meaningless gift to buy affection that he didn't really think about.
Furthermore, it's said in the novel that the dress code is something limited to the children, and the adults aren't informed or involved with (adults have their own costume themes). So even if he did know that she was going to wear it to the party, he wouldn't know that it clashed with the party's theme until they got there.
...which is basically the ONLY thing he's innocent of in the entire novel, because Dad is a firm believer in "Sink or Swim." So even if he DID knew, it wouldn't change anything, because he would also (incorrectly) assume that she was informed of the dress code beforehand, deliberately made a poor costume decision, and therefore she has to save herself. (Because he won't get involved in children squabbles.)
I hate how the fates pair was r@ped and now that he found his one he was taken away from him by another omega, like yeah I love Asusa and Kae but idk it just doesn’t feel right
